Traditional Chinese medicine(TCM) processing is a specialized pharmaceutical technique with the primary objective of reducing the toxicity of medicinal substances. Euphorbia pekinensis, E. ebracteolata, and E. fischeriana, all belonging to Euphorbiaceae, are classified as drastic purgative herbs, traditionally used for eliminating retained water, reducing swelling, resolving toxicity, and dispersing masses. However, these herbs are also associated with adverse effects such as abdominal pain and diarrhea. Accordingly, they are commonly processed with vinegar, milk, or Terminalia chebula decoction to reduce the toxicity. This review summarizes the chemical constituents, pharmacological activities, historical evolution of processing methods, and detoxification mechanisms of the three toxic Euphorbia species. The primary toxic constituents are terpenoids. Specifically, E. ebracteolata and E. fischeriana are rich in diterpenoids, while E. pekinensis contains diterpenoids, triterpenoids, and sesquiterpenoids. Studies have shown that vinegar processing promotes structural transformations of diterpenoids, including ether bond hydrolysis, lactone ring opening, esterification, oxidation, and epoxide ring cleavage, thereby reducing the content and toxicity of these compounds. Milk processing facilitates the dissolution of toxic components into the residual liquid of excipients, leading to decreases in their concentrations in the final decoction pieces. Processing with T. chebula decoction raises the levels of tannin-derived phenolic acids, which antagonize the adverse effects of the intestine. These findings reveal a shared detoxification pattern among the three toxic herbs. Accordingly, this review proposes the concept of a shared detoxification mechanism for toxic herbs belonging to the same family or genus. That is, toxic herbs belonging to the same taxon often exhibit similar toxicological profiles and can undergo detoxification through the same processing methods, reflecting common underlying mechanisms. Investigating such shared mechanisms across multiple species of the same genus offers a promising research strategy. Ultimately, the research into processing-induced detoxification mechanisms provides both theoretical and practical support for ensuring the safety of toxic TCM.

OBJECTIVES: To explore the efficacy and adverse reactions of nusinersen combined with risdiplam in the treatment of spinal muscular atrophy (SMA). METHODS: A retrospective analysis was conducted on the clinical data of 10 pediatric SMA patients treated with nusinersen combined with risdiplam at the Children's Medical Center of Xiangya Hospital, Central South University. RESULTS: Among the 10 SMA patients, there were 4 with type I, 4 with type II, and 2 with type III. Nine patients initially received nusinersen monotherapy, while 1 patient received nusinersen combined with risdiplam. The median duration of combination therapy with nusinersen and risdiplam for the 10 patients was 10.5 months (range: 0.5-20.0 months), with 6 patients undergoing combination therapy for more than 6 months, showing improvements in motor and/or respiratory function. The remaining 4 patients had combination treatment durations of 0.5, 1.0, 1.3, and 4.0 months, respectively, with no significant overall improvement. After combined treatment, 5 patients experienced skin hyperpigmentation, 2 had lumbar puncture site pain, 1 experienced vomiting, 1 had increased sputum production, and 1 had reduced total sleep time. All adverse reactions were mild and did not require medical intervention. CONCLUSIONS Nusinersen combined with risdiplam demonstrates efficacy in the treatment of SMA, and no significant adverse reactions have been observed.

Case 1 was a 7-year-old girl; Case 2 was her 3-year-old younger brother. Both children developed pink urine shortly after birth and exhibited blistering on photo-exposed areas (face and hands), followed by ulceration, crusting, scarring, and joint contractures leading to impaired mobility. Genetic testing in both patients identified a homozygous variant in the UROS gene, c.776T>C (p.Leu259Pro), confirming autosomal recessive congenital erythropoietic porphyria due to UROS mutations. This case report highlights that congenital erythropoietic porphyria should be considered in infants and young children with unexplained hemolytic anemia, pink urine, and severe photosensitive dermatitis. Early genetic testing is recommended to facilitate timely intervention and improve outcomes.

Objective To evaluate safety and efficacy of linaclotide combined with polyethylene glycol(PEG)for bowel preparation.Methods A total of 612 patients from Department of Gastroenterology at the Affiliated Hospital of Qingdao University for colonoscopy examination from January to June 2023 were selected.They were divided into group 1(1 L PEG+2 L PEG),group 2(linaclotide+2 L PEG)and group 3(1 L PEG+linaclotide+1 L PEG)by random number table method,with 204 cases in each group.The Ottawa Bowel Preparation Quality Scale(OBPS),the insertion time of colonoscopy,the time of the first defecation,the frequency of defecations,the occurrence of adverse effects and patients'tolerability were compared among the three groups.Results A total of 601 patients completed bowel preparation and accepted colonoscopy.Group 1 exhibited no statistically significant differences to group 2 with regards to OBPS and insertion time.However,Group 2 demonstrated a shorter duration for the time of the first defecation in comparison to both group 1 and group 3(P＜0.05).Group 1 displayed a higher frequency of defecations as compared to Group 2 and Group 3(P＜0.05).The incidence of adverse reactions was significantly lower in group 2 and group 3 than in group 1(P＜0.05).The overall tolerance score of patients in group 1 was low-er than that in group 2 and group 3(P＜0.05).Conclusions The effect of combining 2 L PEG with 290 μg of lina-clotide for bowel preparation before colonoscopy is similar to that of 3 L PEG.It can reduce the incidence of adverse reactions and patients exhibit good tolerance.For patients who are intolerant to a single high-dose administration of PEG,they need divided-dose regimen of 2 L PEG in combination with linaclotide.

Objective To investigate the effects of neuronal pentraxin 2(Nptx2)on complement system,microglia activation and synaptic density in mice with Alzheimer's disease(AD).Methods Six-months-old APPswe/PS1dE9 double transgenic mice were divided into model group(intracerebroventricularly injected with AAV-Veh 1 × 1010 GC)and model+AAV-Nptx2 group(intracerebroventricularly injected with AAV-Nptx2 1 × 1010 GC),6-months-old wild-type mice were divided into control group(intracerebroventricularly injected with AAV-Veh 1 × 1010 GC)and control+AAV-Nptx2 group(intracerebroventricularly injected with AAV-Nptx2 1 x 1010 GC),with 12 mice in each group.One month later,the cognitive function of mice in each group was evaluated by Morris Water Maze test.The expression levels of Nptx2 and Iba1 proteins were measured by Western blot,the contents of complement related proteins were measured by enzyme linked immunosorbent assay,and the synaptic plasticity was evaluated by Golgi staining.Results The resident time in the platform quadrant of control,control+AAV-Nptx2,model and model+AAV-Nptx2 groups were(44.72±10.92),(53.32±10.29),(21.92±3.80)and(36.47±6.41)s;the number of crossing the platform were 10.08±2.64,9.58±3.09,2.25±1.29 and 5.92±1.38;the relative expression levels of Nptx2 protein were 0.33±0.06,0.63±0.10,0.09±0.03 and 0.57±0.22;the relative expression levels of Iba1 protein were 0.17±0.06,0.23±0.08,0.97±0.16 and 0.40±0.14;the synaptic densities were 22.75±4.27,29.25±4.78,8.25±2.99 and 23.75±4.86.Compared with the model group,the differences of above indexes in the model+AAV-Nptx2 and control groups were statistically significant(all P＜0.05).Conclusion Overexpression of Nptx2 protein can inhibit the activation of complement system,reduce the activation of microglia,and increase the synaptic density to alleviate cognitive impairment in AD mice.

OBJECTIVES: To study the factors influencing the short-term (28 days) efficacy of initial adrenocorticotropic hormone (ACTH) therapy for infantile epileptic spasms syndrome (IESS), as well as the factors influencing recurrence and prognosis. METHODS: The clinical data were collected from the children with IESS who received ACTH therapy for the first time in the Department of Pediatric Neurology, Xiangya Hospital of Central South University, from April 2008 to January 2018 and were followed up for ≥2 years. The multivariate logistic regression analysis was used to evaluate the factors influencing the short-term efficacy of ACTH therapy, recurrence, and long-term prognosis. RESULTS: ACTH therapy achieved a control rate of seizures of 55.5% (111/200) on day 28 of treatment. Of the 111 children, 75 (67.6%) had no recurrence of seizures within 12 months of follow-up. The possibility of seizure control on day 28 of ACTH therapy in the children without focal seizures was 2.463 times that in those with focal seizures (P<0.05). The possibility of seizure control on day 28 of ACTH therapy in the children without hypsarrhythmia on electroencephalography on day 14 of ACTH therapy was 2.415 times that in those with hypsarrhythmia (P<0.05). The possibility of recurrence within 12 months after treatment was increased by 11.8% for every 1-month increase in the course of the disease (P<0.05). The possibility of moderate or severe developmental retardation or death in the children without seizure control after 28 days of ACTH therapy was 8.314 times that in those with seizure control (P<0.05). The possibility of moderate or severe developmental retardation or death in the children with structural etiology was 14.448 times that in those with unknown etiology (P<0.05). CONCLUSIONS Presence or absence of focal seizures and whether hypsarrhythmia disappears after 14 days of treatment can be used as predictors for the short-term efficacy of ACTH therapy, while the course of disease before treatment can be used as the predictor for recurrence after seizure control by ACTH therapy. The prognosis of IESS children is associated with etiology, and early control of seizures after ACTH therapy can improve long-term prognosis.

AIM: To investigate the impact of meteorological factors in different environments in the eastern and western regions of China on the incidence of lipid-abnormal dry eye.METHODS: This is a multicenter retrospective study. From March 1, 2021 to February 28, 2022, all patients with dry eye were selected from the ophthalmology clinic of Nanjing Hospital of Chinese Medicine Affiliated to Nanjing University of Chinese Medicine and Friendship Hospital of Xinjiang Yili Kazakh Autonomous Prefecture. General data(gender, age, employment and education)and climate data for outdoor environments(temperature, humidity, air quality index and wind)on the day of the visit were collected. Patients who met the inclusion and exclusion criteria were selected. Single factor, multiple factors and nonlinear model analysis were applied to identify environmental factors of lipid-abnormal dry eye in both regions.RESULTS: There was no significant difference in the incidence of lipid-abnormal dry eye between Nanjing and Yili in different seasons. The incidence of lipid-abnormal dry eye in Yili was significantly higher in all seasons than in Nanjing(P<0.001). The results of univariate research showed that the factors affecting the incidence of lipid-abnormal dry eye were gender, employment, humidity, air quality, and wind. The results of multivariate Logistic regression analysis showed that humidity, temperature and air quality were statistically significant, and remained significant after adjusting for the three confounding factors of age, gender and employment situation. Nonlinear analysis showed that the probability of lipid-abnormal dry eye increased with the decrease of temperature when the temperature was below 10℃; within the range of 10℃～15℃, the probability of lipid-abnormal dry eye tended to stabilize. When the temperature exceeded 15℃, the probability of lipid-abnormal dry eye increased with the increase of temperature. Humidity was negatively correlated with the onset of lipid-abnormal dry eye. As humidity increased, the probability of lipid-abnormal dry eye decreased.CONCLUSIONS: The risk of lipid-abnormal dry eye in Yili is higher than that in Nanjing throughout the four seasons. Humidity, temperature, air quality and other environmental and meteorological factors can all affect the incidence of lipid-abnormal dry eye.

Alzheimer's disease(AD) patients in China have been surging, and the resultant medical burden and care demand have a huge impact on the development of individuals, families, and the society. The active component compound of Epimedii Folium, Astragali Radix, and Puerariae Lobatae Radix(YHG) can regulate the expression of iron metabolism-related proteins to inhibit brain iron overload and relieve hypofunction of central nervous system in AD patients. Hepcidin is an important target regulating iron metabolism. This study investigated the effect of YHG on the expression of a disintegrin and metalloprotease-17(ADAM17), a key enzyme in the hydrolysis of β amyloid precursor protein(APP) in HT22 cells, by mediating hepcidin. To be specific, HT22 cells were cultured in vitro, followed by liposome-mediated siRNA transfection to silence the expression of hepcidin. Real-time PCR and Western blot were performed to examine the silencing result and the effect of YHG on hepcidin in AD cell model. HT22 cells were randomized into 7 groups: control group, Aβ25-35 induction(Aβ) group, hepcidin-siRNA(siRNA) group, Aβ25-35 + hepcidin-siRNA(Aβ + siRNA) group, Aβ25-35+YHG(Aβ+YHG) group, hepcidin-siRNA+YHG(siRNA+YHG) group, Aβ25-35+hepcidin-siRNA+YHG(Aβ+siRNA+YHG) group. The expression of ADAM17 mRNA in cells was detected by real-time PCR, and the expression of ADAM17 protein by immunofluorescence and Western blot. Immunofluorescence showed that the ADAM17 protein expression was lower in the Aβ group, siRNA group, and Aβ+siRNA group than in the control group(P<0.05) and the expression was lower in the Aβ+siRNA group(P<0.05) and higher in the Aβ+YHG group(P<0.05) than in the Aβ group. Moreover, the ADAM17 protein expression was lower in the Aβ+siRNA group(P<0.05) and higher in the siRNA+YHG group(P< 0.05) than in the siRNA group. The expression was higher in the Aβ+siRNA+YHG group than in the Aβ+siRNA group(P<0.05). The results of Western blot and real-time PCR were consistent with those of immunofluorescence. The experiment showed that YHG induced hepcidin to up-regulate the expression of ADAM17 in AD cell model and promote the activation of non-starch metabolic pathways, which might be the internal mechanism of YHG in preventing and treating AD.
